SOURCE: Little to no injector pulse only when starter is engaged

95-97 Maximas had a problem where condensation from the A/C would accumulate in the a/c evaporator case from the drain becoming restricted or blocked, When this would occur, condensation would drip onto the ECM and a problem would develop with misfire and/or starting. I would look at the ECM where the harness connects to it for corrosion problems. If you find it, there is a chemical spray which can be used to clean the terminals and/or you can clean them, although it is time consuming and difficult to due because of how small the terminals are. After things are cleaned up, lightly coat the connections with a dielectric grease. This will prevent electrolysis.I believe you can buy these at Radio shack and possibly at an automotive parts supplier.
Also a drop in voltage during the cranking phase will cause a weak spark. Your ignition is what pulses the injectors. It takes a minimum of 9.6 volts, but ideally you want at least 10.5 or more during the cranking phase if you want to get a spark worth anything. Check the voltage on the primary side of the coil while cranking the engine.
I'll watch to see if things work out for you, let me know. ....mybunkey

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA
